FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent N 0. 670,139, dated March 19, 1901.

Application filed October 26, 1900. serial No. 34,450. (No model.)

To 0% whom it may concern:

Be it known that I, WARREN OMEY, a citizen of the United States, residing at Temple, in thecountyof Clare and State of Michigan, have invented a new and useful Fire-Escape, of which the following is a specification.

This invention relates to fire-escapes, and has for its object to provide an improved portable device of this character which may be conveniently carried in a valise and is arranged for application to a window-sill, so that a person may lower himself from an upper story of a building without the aid of other persons. It is furthermore designed to have the attaching parts of the device both detachable and adjustable, so that they may be compactly folded and also that the device may be accommodated to window-sills of different widths.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanyingdrawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims Without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a side elevation of the device applied to the window-sill of a building. Fig. 2 is a view at substantially right angles to Fig. 1 and showing the wall of the building in section to illustrate the connection of the device with the window-sill.

Corresponding parts are designated by like characters of reference in both figures of the drawings.

Referring to the drawings, 1 and 2 designate opposite substantially triangular frameplates, which are connected at their upper ends and also provided with an opening 3, formed through said connected portions and located at the uppermost corner of the frame. Located between the plates are the opposite grooved pulleys 4 and 5, which are of substantially the same size and are journaled in the opposite lower corners of the frame. A

larger grooved pulley6 is journaled between the frame-plates and substantially midway between the pulley and the opening 3 in the upper corner of the frame, whereby all of the pulleys or wheels are in substantially the same plane and are housed between the opposite sides of the frame.

A cable 7 is provided at one end with a stirrup or seat 8, from which said cable extends upwardly andaround the lowermost pulley 4, from the inner side thereof, thence from the lower side of the pulley inwardly and around the opposite pulley 5, from the outerside thereof, thence inwardly and around the larger pulley; from the lowerside thereof,and finally downwardly through the frame from the-innenedge of the uppermost or larger pulley, this latter portion of the cable being free for manipulation by the person descending in the stirrup or seat.

To support this device upon a building, there is provided a bracket-bar 9, which is provided at its lower end with a transverse foot 10 to rest flat against the outer side of the wall of a building 11, as best indicated in Fig. 2 of the drawings, and having a hook 12 at the upper end of the bar. This bar inclines upwardly and outwardly from the foot, so that the hook end thereof is disposed outwardly from the wall. A transverse bracearm 13 is employed to connect the intermediate portion of the bracket-bar to the window-sill 14, and this arm has the opposite terminal hooks 15 and 16 for engagement, respectively, with the bracket-bar and the inner edge of the window-sill. These hooks are disposed in planes at substantially right angles to each other, the outer bracket-engaging hook being horizontally disposed, so as to be engaged with one of a plurality of perforations 17, formed in the bracket-bar. It is preferable to have the brace-arm formed in longitudinal sections, one of which has alongitudinal slot 18 and the other is provided with one or more lateral fastenings 19, extending through the slot of the former section, whereby the arm has a longitudinal and extensible adjustment to accommodate the device to window-sills of different widths. The adjustment of the bracket vertically by means of the perforations therein is to permit of the foot of the bracket being placed at different distances below the window-sill, according to the depth thereof, and to accommodate the device to any obstructions which may be upon the outer side of the sill or the wall.

In using the device the bracket and the brace-arm thereof are applied to the wall and the window-sill, as explained, after which the pulley-frame is applied to the bracket by re ceiving the hook thereof in the suspending opening 3 in the upper end of the frame, when the device is in condition for use. The op erator climbs out through the window and takes hold of the free portion of the cable, and finally places himself in the seat or stirrup, after which it is a simple matter to lower himself by manipulating the free portion of the cable, as will be understood. When he reaches a place of safety, the seat may be returned to the window for another person by pulling downwardly upon the free portion of the cable.

It will be observed that the cable-supporting pulley 4 is in substantially vertical alinement with the larger cable-controllin g pulley b, and the cable is wrapped about these pulleys, so that its opposite end portions may hang from the inner edges thereof, whereby the opposite portions of the cable are close together for convenient manipulation. Also the tension-pulley 5 is located at one side and intermediate of the two other pulleys, so as to insure a tight engagement of the cable with these pulleys.

What is claimed is- 1. A fire-escape, comprising a bar, having a lower terminal wall-engaging foot, and an upper terminal hook, a lateral brace having a detachable engagement with the intermediate portion of the bar, and also being adjustable longitudinally thereof, whereby the latter may be adjustably inclined, the opposite end of the brace having a window-sill attachment, and an elevating device detachably hung from the upper terminal hook of the bar.

2. A fire-escape, comprising a bracket having a plurality of interm ediately-disposed perforations, and a foot for engagement with the wall of a building, a lateral brace formed in longitudinal sections, one of which has a longitudinal slot, and the other has an adjustable fastening entering said slot, a hook at the outer end of the brace and removably engaging one of the perforations in the bracket, and a hook at the inner end of the brace for engagement with a window-sill, and an elevating device suspended from the bracket.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

WARREN OMEY.
